mec1322: Deassert iRESET_OUT on init
mec1322: Deassert iRESET_OUT on init

iRESET_OUT must be deasserted before the host can boot, and it's also
the gating source of the internal nSIO_RESET signal. There is a delay
between deasserting iRESET_OUT and nSIO_RESET inactivated, so let's
deassert iRESET_OUT as early as possible.

BUG=chrome-os-partner:24107
TEST=Boot EVB and check iRESET_OUT value
BRANCH=None
